(9H-fluoren-9-yl)methyl (4-aminobutyl)carbamate hydrobromide CAS 352235-99-5

Description

The occurrence of (9H-fluoren-9-yl)methyl (4-aminobutyl)carbamate hydrobromide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(9H-fluoren-9-yl)methyl (4-aminobutyl)carbamate hydrobromide (CAS 352235-99-5), molecular formula C19H22N2O2HBr and molecular weight 391.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H22N2O2HBr, (9H-fluoren-9-yl)methyl (4-aminobutyl)carbamate hydrobromide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 391.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
